The half-life of a radioactive element is 8 days. The fraction remaining after 32 days is:
Show Hint
Remaining fraction = \((1/2)^n\).
Updated On: Jan 5, 2026
- \(1/2\)
- \(1/4\)
- \(1/8\)
- \(1/16\)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
\[
32\ \text{days} = 4\ \text{half-lives}
\Rightarrow \left(\frac12\right)^4=\frac1{16}
\]

- (a) Consider the so-called ‘D-T reaction’ (Deuterium-Tritium reaction).
In a thermonuclear fusion reactor, the following nuclear reaction occurs: \[ \ ^{2}_1 \text{H} + \ ^{3}_1 \text{H} \longrightarrow \ ^{4}_2 \text{He} + \ ^{1}_0 \text{n} + Q \] Find the amount of energy released in the reaction.
% Given data Given:
\( m\left(^{2}_1 \text{H}\right) = 2.014102 \, \text{u} \)
\( m\left(^{3}_1 \text{H}\right) = 3.016049 \, \text{u} \)
\( m\left(^{4}_2 \text{He}\right) = 4.002603 \, \text{u} \)
